"In that case, he'll have to pay for his whistle, sir."
"You mean in connection with the conspiracy?"
"Yes, and perhaps with the murder of Clear; but we don't know if the so-called Wrent committed the crime.
For such reason, Mr. Denzil, I wish to overhear what he says to Mrs. Clear. It is as well to give him enough rope to hang himself with."
"Can you trust Mrs. Clear?"
"Absolutely.
She knows on which side her bread is buttered.
Her only chance of getting free from her share of the matter is to turn Queen's evidence, and she intends to do so."
"What did she say about Vrain being Wrent?"
"Well, sir," said Link, putting his head on one side, and looking at Lucian with an odd expression, "you had better wait till the man's caught before I answer that question.
Then, maybe, you won't require an answer."
"It is very probable I won't," replied Lucian drily. "What time am I to see you to-night?"
"I'll call for you at nine o'clock sharp, and we'll go across to the house at once.
I have the key in my pocket now. Peacock gave it to me this morning.
The scene will be quite dramatic."
"I hope it won't prove to be Vrain," said Lucian restlessly, for he thought how grieved Diana would be.
"I hope not," answered Link curtly, "but there's no knowing.
However, if the old man does get into trouble he can plead insanity.
His having been in the asylum of Jorce is a strong card for him to play.
Good-day, Mr. Denzil.
I'll see you to-night at nine o'clock sharp."
"Good-day," replied Lucian, and the pair parted for the time being.
Lucian did not go near Diana that day.
In the first place, he did not wish to see Lydia, for whom he had no great love; and in the second, he was afraid to speak to Diana as to the possibility of her father being Wrent.
Diana, as a good daughter should, held firmly to the idea that her father could not behave in such a way; and as a sensible woman, she did not think that a man with so few of his senses about him could have acted the dual part with which he was credited without, in some measure, betraying himself.
Lucian was somewhat of this opinion himself, yet he had an uneasy feeling that Vrain might prove to be the culprit.
The fact of Vrain's being often away from Mrs. Clear's house in Bayswater, and Wrent absent in the same way from Mrs. Bensusan's house in Jersey Street, appeared strange, and argued a connection between the two.
Again, the resemblance between them was most extraordinary and unaccountable.
On the whole, Lucian was not satisfied in his mind as to what would be the end of the matter, and had he known Mrs. Clear's address he would have gone to question her about it.
But only Link knew where the woman was to be found, and kept that information to himself—especially from Denzil.
Now that he had the reins once more in his hands, he did not intend that the barrister should take them again.
Punctual to the minute, Link, in a state of subdued excitement, came to Lucian's rooms.
Already he had sent his two policemen over to the house, into which he had instructed them to enter in the quietest and most unostentatious manner, and now came to escort the barrister across.
Lucian put on his hat at once, and the two walked out into the dark night, for dark it was, with no moon, few stars, and a great many clouds.
A most satisfactory night for their purpose.
"All the better," said Link, casting a look round the deserted square; "all the better for our little game.
I wish to secure this fellow as quietly as possible.
Here's the door open—in with you, Mr. Denzil!"
According to instructions, a policeman had waited behind the closed door, and at the one sharp knock of his superior opened it at once so that the two slipped in as speedily as possible.
Link had a dark-lantern, which he used carefully, so that no light could be seen from the window looking on to the square; and with his three companions he went into the back room which had formerly been used by Clear as a sleeping apartment.
Here the two policemen stationed themselves in one corner; and Link, with Lucian, waited near the door leading into the sitting-room, so as to be ready for Mrs. Clear.
All was so dark and lonely and silent that Lucian's nerves became over-strained, and it was as much as he could do to prevent himself from trembling violently.
In a whisper he conversed with Link.
"Have you heard anything of that girl Rhoda?" he asked.
"We have traced her to Berkshire," whispered Link. "She went back to her gypsy kinsfolk, you know.
I dare say we'll manage to lay hands on her sooner or later."
"She is an accomplice of Wrent's, I believe."
"So do I, and I hope to make him confess as much to-night.
Hush!"
Suddenly Link had laid his clasp on Lucian's wrist to command silence, and the next moment they heard the swish-swish of a woman's dress coming along the passage.
